Abstract—Microbial products have been used by human for a long time. One of the products is color. Researches were done to find more products that can be useful. Therefore, this research studied about color extracted from mycelium of Neurospora crassa, fungus in phylum Ascomycota, which has not been used before. Mycelium was extracted with absolute ethanol. The color was orange. The optimum wavelength for the colorimetric measurement was 420.5 nm and the optical density (O.D.) or absorbance of the color extract was 0.222. From the result of experiment, it found that the appropriate solution to separate the colorants extracted to pure substance for studying the composition is acetone and chloroform. After separated with TLC aluminum sheet, there are five groups of separable substances.

Index Terms—Color, composition, mycelium, Neurospora.
